A police Sargent grew impatient when the person in front of him in the drive-thru line at McDonald's was moving too slowly.

DeKalb County police Sgt. Scott Biumi is charged with felony aggravated assault after allegedly pulling a gun on a customer in the line.The driver, 18-year-old Ryan Mash, told NBC affiliate WIZ-TV that he had no idea the man was a police officer. According to Mash, the man accused him of "holding up the line," then got out of his car and threatened him by sticking a gun to his neck. Biumi was apparently angry at the amount of time it was taking for him to get his food.

Biumi is a 20-year veteran of the DeKalb County Police Department and has been placed under administrative leave with pay while the incident is investigated.
